XAML ObjectDataProvider, ObjectType Error

[rocksam2003]

I'm a trying to instantiate an object (that was created in C#) in XAML using the ObjectDataProvi der. Unfortunately, I'm receiving the following error: "The type reference cannot find a public type named 'TYPENAME'". I have a .cs file of the same name as the the TYPENAME.

Here's my XAML:

<Window x:Class="PROJECTNAME.PROJECTFILE"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:dg="http://schemas.microsoft.com/wpf/2008/toolkit"
        xmlns:local="clr-namespace:PROJECTNAME"
        Title="PROJECTFILE" Height="500" Width="500">
    <Window.Resources>
        <ResourceDictionary>
            <ObjectDataProvider x:Key="NAME1" ObjectType="{x:Type TYPENAME}"/>
            <ObjectDataProvider x:Key="NAME2" ObjectInstance="{StaticResource TYPENAME}" MethodName="METHODNAME"/>
        </ResourceDictionary>
    </Window.Resources>
    <Grid Height="375">
        <DockPanel DataContext="{Binding Source={StaticResource TYPENAME}}" Width="440" Margin="10,20,191,35">
            <dg:DataGrid Name="DG" ItemsSource="{Binding}"/>
        </DockPanel>
        <DockPanel Width="85" Height="25" Margin="0,350,0,0">
            <Frame Name="Frame"/>
            <Button Content="See Posts Info" Click="Button_Click"/>
        </DockPanel>
    </Grid>
</Window>

Here's the C# file for TYPENAME:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Data;

namespace PROJECTNAME
{
    class TYPENAME
    {
        private AccesDBDataSet data_set;
        private AccesDBDataSetTableAdapters.tblTYPENAMETableAdapter TYPENAMEAdapter;

        public TYPENAME()
        {
            data_set = new AccesDBDataSet();
            DataTable tblTYPENAME = data_set.Tables[1];
            TYPENAMEAdapter = new AccesDBDataSetTableAdapters.TYPENAMEAdapterTableAdapter();
            TYPENAMEAdapter.Fill(data_set.tblTYPENAMEAdapter);
        }

        public DataView METHODNAME()
        {
            return data_set.tblTYPENAMEAdapter.DefaultView;
        }
    }
}

So, why exactly is TYPENAME unrecognized in line 9 of the XAML? Am I formatting it incorrectly? I tried setting it up as

<ObjectDataProvider x:Key="NAME1" ObjectType="{x:Type local:TYPENAME}"/>

but that caused the same bug.

Thanks for the help!

I'm not sure why you are seeing the error but I noticed that your source is incorrect for your DockPanel in your XAML. You are attempting to bind to a Static Resource called TYPENAME but the key for that resource is actually NAME2.

Try fixing your binding and see if it fixes the problem.
If it doesn't I'll try and reproduce the problem here.

That actually didn't fix it.

Thanks, though; you saved me an error later one, I'm sure.

I'm not sure what you are doing wrong because I cannot reproduce it.

I added a window to my project called ProjectFile (same as yours except not in all caps).

I then added a class called TypeName and used the normal DataSet instead of the access one since I don't have that available.

Lastly, I copied and pasted your XAML markup and made some binding adjustments to get it to work properly (as per the corrections I suggested before).

I am unable to reproduce the problem that you are having.

This is my XAML

<Window x:Class="ProjectFile"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:local="clr-namespace:ProjectName"
        Title="ProjectFile" Height="300" Width="300">
    <Window.Resources>
        <ResourceDictionary>
            <ObjectDataProvider x:Key="NAME1" ObjectType="{x:Type local:TypeName}"/>
            <ObjectDataProvider x:Key="NAME2" ObjectInstance="{StaticResource NAME1}" MethodName="MethodName"/>
        </ResourceDictionary>
    </Window.Resources>
    <Grid Height="375">
        <DockPanel DataContext="{Binding Source={StaticResource NAME2}}" Width="440" Margin="10,20,191,35">
            <DataGrid Name="DG" ItemsSource="{Binding}"/>
        </DockPanel>
        <DockPanel Width="85" Height="25" Margin="0,350,0,0">
            <Frame Name="Frame"/>
            <Button Content="See Posts Info" />
        </DockPanel>
    </Grid>
</Window>

This is my code for the TypeName class:

(VB)

Class TypeName
    Private data_set As System.Data.DataSet
    Public Sub New()
        data_set = New System.Data.DataSet()
        Dim tblTypeName As New System.Data.DataTable
        tblTypeName.Columns.Add("Col1")
        tblTypeName.Columns.Add("Col2")
        For i As Integer = 0 To 10
            Dim dr As System.Data.DataRow = tblTypeName.NewRow
            dr(0) = String.Format("{0} ", i.ToString)
            dr(1) = String.Format("{0} ", i.ToString)
            tblTypeName.Rows.Add(dr)
        Next
        data_set.Tables.Add(tblTypeName)
    End Sub

    Public Function MethodName() As System.Data.DataView
        Return data_set.Tables(0).DefaultView
    End Function
End Class

(C#)

class TypeName
{
	private System.Data.DataSet data_set;
	public TypeName()
	{
		data_set = new System.Data.DataSet();
		System.Data.DataTable tblTypeName = new System.Data.DataTable();
		tblTypeName.Columns.Add("Col1");
		tblTypeName.Columns.Add("Col2");
		for (int i = 0; i <= 10; i++) {
			System.Data.DataRow dr = tblTypeName.NewRow();
			dr[0] = string.Format("{0} ", i.ToString());
			dr[1] = string.Format("{0} ", i.ToString());
			tblTypeName.Rows.Add(dr);
		}
		data_set.Tables.Add(tblTypeName);
	}

	public System.Data.DataView MethodName()
	{
		return data_set.Tables[0].DefaultView;
	}
}

The only thing that I can think that is going wrong is that something didn't compile properly and so you are getting a strange error.
